HAROLD BERNICE PnY'roN, or JACKSONVILLE, FLORIDA l rrnnrnoor MAIL BAG Application led September This invention aims to provide a mail bag so constructed that its contents will not be likely to be damaged by fire. Another object of the invention is to provide a novel gg means whereby a re extinguishing gas will be liberated within the mail bag when the temperature within the mail bag rises. A further object of the invention is to provide novel means for holdinga receptacle in the l mail bag and to supply means whereby the receptacle may be removed for recharging.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that sort to which the v 15, present invention appertains.

bWith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction, hereinafter described and claimed, it' being understood that changes may be made in the precise embodiment of the invention, within the scope of what is claimed, without departing v from the spirit of the invention.

In the drawings: y

Figure 1 shows in vertical longitudinal section, a mail bag constructed in accord-V ance with the invention;

Figure 2 is a cross section on the line 2-2 of Figure 1;

Figure 3 is a fragmental longitudinal section showing a modification.

In carrying out the invention, there is provided a mail bag 1, made of flexible, fireproof material, asbestos entering into the composition of the bag, if that ingredient is considered desirable. marks any suitable means whereby the mail bag may be held closed. n

i The mail bag includes a bottom 2. W'ithin the mail bag 1 is located a receptacle 3 carrying a filling nozzle 15 provided with a fuse 16 which will melt at a very low temperature. The receptacle 3 preferably is made of metal and is adapted to withstand considerable pressure. Any means may be rovided JI'or holding it in place in the mail ag 1.

The receptacle 3 may be supplied with an The numeral 2() 3, 1929. Serial No. 390,025.

outstanding rim 4. A ring 5, preferably made of metal, is held on a base plate 6 by securing elements 7, the base plate 6 being made of metal which is a goed conductor of heat. The attaching elements that hold the '155 base plate 6 on the bottom 2 are marked by the numeral 19. The `base plate 6 has .an opening 8 in which is located a removable closure 9. The closure 9 engages the rim at of thel receptacle 3 and holds the receptacle in place in the mail bag. Securing devices 10 connect the closure 9 with the ring 5. The securing devices 10 may be screws having their heads located inside the bag 1, so that a person cannot crack the bag from the fc5 outside and remove the contents.

The closure 9, like'the base plate` 6, is made of metal, which is a goed conductor. By having the base plate 6 and the closure 9 made of metal, these parts are well .7e adapted towithstand hard use to which a mail bag is subjected when it is dragged about. Another advantage in having the base plate 6 and the closure 9 made of metal is that, thereby, heat will be conducted quickly to the receptacle 3 in the event that the temperature outside the bag rises to a point that will endanger the contents of the bag. v

The ring -has an upstanding collar 11. The ring 5 and its collar 11 may be considered asr a part ofthebase plate 6, since they are secured thereto by the tastenings 7 Aftubular guard 12 Vfashioned romvwire netting, or other foraminous material, is secured at its lower end within the collar 11. The guard 12 is closed at its inner end, as shown at V11.11,. l

In practical operation when an undue rise in. temperature occurs, the -fuse 16 melts. The receptacle?) is charged with gas under pressure, the gas being of such a nature that it will put out fires. When Vthe fuse 16 melts, the gas flows from the receptacle 3 into the bag 1, and the contents of the bag are'insured against conflagration. The reason for having the guardV 12 `is to have an opening at the ends-ofthe bag 1, so that the fire extinguishing gas can get at a large proportion of the contents of the bag quickly.

VSi)

Some persons do not care for the guard l2 and it can be omitted, if desired. Such a construction is shown in Figure 3, and in Figure 3, parts hereinbefore described, have been designated by numerals previously used, with the suffix a Although any means may be provided for holding the receptacle 3 in the bag l, the` structure shown in Figure 3 is a good one. Whilst the bag la is opened, the operator takes out the screws a. This sets .the closure 9a free, and the receptacle 3a may be removed, the depleted receptacle being replaced by one which is charged with lire eX- tinguishing gas under pressure. rlhe closure 9a is replaced, the screws 10a are reinserted, and the structure again appears as is shown in Figure 1. l

As has been stated hereinbefore, the screws l0 and 10a are inaccessible from without the bag l, and, therefore, thecontents of the bag are secured against any efforts short of those which would destroy the bag itself,`there being no way of providing against such a danger, either in the present bag, or in any other bag now on the market, or heretofore known. The device shown in the drawings, therefore, presents as much security as might be eX- p'ected, reasonably, Jfrom any device of the class described.

I claim:

l. A mail bag having a mouth and provided on its bottom with a receptacle having an outlet discharging into vthe'bag,thermal means for closing the outlet, and a tubular guard constructed of closely woven foraminous material and closed at its end adjacent the mouth of the bag, the guard being disposed within the bag and about the recep- 40 tacle, the guard extending toward the mouth of the mail bag far enough to permit a discharge of the contents of the receptacle throughout the major portion of the mail in the bag when the thermal means acts to open the outlet of the receptacle. y Y

2. In a device of the class described, ,a mail bag including a base having an opening, a closure for the opening, a receptacle held on the base by the closure, the receptacle being 5G constructed to retain a lire-extinguisher, thermal means located within the bag for closing the receptacle, the bag having a mouth, mechanism for closing the mouthoi:l

the bag at the will of an operator, and means 55., inaccessible from without the bag for hold; ing the closure in place, the receptacle being outwardly removable through the opening when the last-specified means is released, and when the closure is removed.

G3 In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
